Dave Wills, Inc. designs and
develops custom test and support applications to improve
productivity and achieve higher quality results. This enhanced tools
capability allows for the development and testing of complex
products. In addition, these tools are used in the
manufacturing process to perform validation and verification of
U/L and FDA requirements and to test manufactured products prior
to shipment to the customer.

The two screen captures shown
above depict tools developed using National Instruments
LabWindows®,
a Windows-based application. Graphical tools interface to
custom products using RS-232 or USB to capture real-time data
regarding the internal operations of hardware and control loops.
These tools are completely configurable using .ini files and
therefore can be used for families of products by simply
changing parameters in the .ini files.

The tools
include all the standard user interface features such as file
open, save and configuration. Real-time data are plotted
as the data arrives from the hardware. Data can be stored
and replayed. On replay, the plots can be zoomed and
panned, and a cursor point selected. The plot data at the
cursor point are displayed. These same tools can be used
in developing your products.
